Si8540 - HIGH-SIDE CURRENT SENSE AMPLIFIER

Description

The Si8540 is a unidirectional, 36 V (max), high-side current sense amplifier for use in applications requiring current monitoring and/or control.

This device draws bias current from the high-side line to which it is attached, eliminating the need for an external supply.

It measures current from 0.

Features

  • Complete, unidirectional high-side current sense capability.
  • 0.2% full-scale accuracy.
  • +5 to +36 V supply operation.
  • 85 dB power supply rejection.
  • 90 µA max supply current.
  • 9 µA shutdown current.
  • Operating Temperature Range:.
  • 40 to +85 °C.
  • 5-pin SOT-23 package.
  • RoHS-compliant.
